BENJAMIN SHWAYDER, OF DENVER, COLOR-ADD, ASSIGNOR T SI'IWYDER T-RUNK' MFG'. C0., OF DENVER, COLOR'ADO, A CORPORATION OF COLORADO STRAP FOR SUITCSES, ETC.

Application filed April 23;

This i-nvention relates to an improvement in straps for suitcases, traveling bags, trunks, etc., and has for its principal object the pro- Vision of a Strap which will be Strong, fleXible, attractive in appearance, and which can be easily, rapidly and efiiciently manufactured.

Another object of the invention is to provide means in a rubber Strap which will prevent the Strap from stretching and will pre- Vent the buckle tongue from tearing out or enlarging the tongue holes.

Still another object of the invention is to provide a rubber Strap with a fabric or cord reinforcement arranged So that the fabric or cord will not show in the edges of the Strap.

A further object is to' provide means for securing the Strap around the buckle and '29 providing a Strap loop with one operation.

A Still further object is to arrange the buckle so that it may be Vulcanized into the Strap so as to become an integral part thereof.

Other objects and advantages reside in the detail construction of the invention, which is designed for Simplicity, economy, and eifi-` ciency. These will become more apparent from the following description.

In the following detailed description of4 ;O the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all Views of the drawng and throughout the description.

In the drawing:

F ig'. 1 is a plan View of one form of my improved Strap partly broken away to show the interior construction.

F ig. 3 is a similar cross section taken on the line 3-8, Fg. 1.

-Fig. 4 is a diagram illustrating the process of manufacture of one form of my improved Strap.

its entirety by the numeral 10 and' provided withv a Strap buckle 11j having the uual tongue 12;

In the preferred form of my inventio'n,` the Strap is formed as shown Fi. 4;,v`v by eXuding a raw rubber tube 13, from a suitable die or mold and passing a fabric or cord bandlt, into the interior of the tube., The tube is then rolled between suitable rolls 1'5i to press it flat against, the fabi'io hand; 14, and, form a fiat- Shiip Whioh is their vul'oanized by any suitable Vulcanizing process. The Strap may be Vulcanized between molds carryi-Hg any suitable design h as, the groores illustrated at 15- By this method of V'than-11.' facturev, the edges ofthe, fabric 14;, are completely ooh'oalod by an ornamehial rubber envelope 16v, formedf from tube 131 To-prevent the buckle tongue 12,V from tearing the Strap, eyelets 17,. 21,156,- placed' through the fabric band' 14, at the points where buckle holes are desired'. These eyelets will be completely imbedded and vulcanized in the rubber covering 16, as illustrated in `Fig. 2,. During the Vulcanizing process pi-ns may be passed' through the eyelets to mold holes in the Strap or the' holes can be punched after Vulcanization by a suitable multiple die.

In the alternate form` of the invention, illustrated in Fig. 5, a diago'nally woven cord fabric 18, is employed, which ordinarily has Suflicient strengthin itself to prevent the buckle tongue from tearng the openings owing to its vd'iagonal cord construction. dditional reinforcement can be provided, however, by plaoiiis a motallio or other .Sirengthoiiing wi'hers. 159, around the tongue opeiiiiiss and allowing the washers to be Vulcanized into.- ih-o riibhlf Cover 1.6, With the iablio 19- ,In ono. form of the invention the buckle 113 is seoiired to the strop by himiiiig hack o iio exiieiaitv 20, iherootfas 'is' Common in .sm-ap and helt 'ooniiiiotion- The turned hack. exiroiiiity 20` isI Soon-red in Place by iiioaii of. a motallio. holt loop 21,, which passi plotoly around the boli; tormihatihg in tongues which ero, iIiSo.itsii through .the turned back Poiiioii wisi' belt- Pronar ehd heat .live-aid in Bliss as showii iii.. Fis- 3'- By this construction a single member provides the belt with a belt loop and secures the buckle in place in one operation.

In another form of my invention, illustrated in Fig. 6, I secure the buckle to the eX- tremity of the fabric band and vulcanize it into the rubber of the strap at the time the band is vulcanized in place therein as shown at 23.

In another process of forming the strap ,the rolls 15 can be eliminated and the rubber tube exuded through a die with the band 14 simultaneously passing from an opening in the die so that it enters the tube. The tube with its enclosed band is then placed in a rubber mold which presses the tube flat against the band. The tube die should have an elongated cross section so that it will snugly inclose the band immediately upon leaving the die.

While specific forms of the improvement have been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention. v

Having thus described the invention, what I claim and desire secured by Letters Patent 1. A strap comprising a fabric band; a rubber envelope completely surrounding both faces and edges of said fabric band; a buckle secured at one extremity of said strap there being a series of buckle openings provided adjacent the other extremity thereof; and strengthening members adjacent said band and surrounding said buckle openings, said members being vulcanized into the interior of said rubber envelope.

2. A strap comprising a fabric band a rubber envelope completely surrounding both faces and edges of said fabric band; a buokle secured at one extremity of said strap there being a series of buckle openings provided adjacent the other extremity thereof; and annular metallic members adj acent said band and surrounding said buckle openings, said members being vulcanized into the interior of said rubber envelope.

8. A strap comprising a fabric band; a rubber envelope completely surrounding both faces and edges'of said fabric band; a buckle secured at one extremity of said strap there being a series of buckle openings provided adjacent the other extremity thereof; and eyelets clamped to said .band and surrounding said openings; said eyelets being vulcanized into the interior of said rubber envelope.

ll. A strap comprising a fabric band; a rubber envelope completely surrounding both faces and edges of said fabric band; a buckle secured to one extremity of said strap by a turned'back portion of that extremity and means for securing said turned-back portion in place, said means comprising a belt loop,

the extremities ,of which pass around to the rear face of said strap and return through both the turned back portion and the strap proper to clamp against the front face thereof.

5. Means for securing the turned back portion of a belt in place and at the same time providing a strap loop comprising a metallic member arranged in spaced relation with the front face of said belt to form a strap loop; extremities on said member extending rearwardly at each edge oflsaid belt and inwardly across the rear face thereof; and looking portions on said eXtremities adapted to extend forwardly through both said belt and said turned back portion and be clamped against the forward face of said belt.

In testimony whereof, I afiix my signature.
